Abstract

The present article provides an overview of developments in nonpolar‐oriented GaN‐based materials as polarized light emitters over the past 15 years. The strong interest in nonpolar materials emerged around 1996, but nonpolar‐oriented light‐emitting diodes were not demonstrated until 2004. The later technological key achievement was the commercialization of nonpolar‐oriented bulk GaN substrates; it is now feasible to discuss the electronic band structure of such high‐quality nonpolar GaN as well as device applications of polarized light emitters.
